SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the manual work of connecting SendGrid to a remote Hermes agent so transactional email can be configured safely from an AI coding agent.

Core Features & Use Cases

  • Sets up SendGrid over SSH with a restricted Mail Send API key and a verified sender identity.
  • Supports two wiring paths: direct REST API usage by default, or an opt-in community MCP server when requested.
  • Handles idempotent setup, scope validation, gateway reloads, smoke tests, and rollback so the integration can be repeated safely.
  • Useful when you need your Hermes VPS to send account emails, notifications, or test messages without hand-editing server config.

Quick Start

Ask the agent to connect SendGrid to your Hermes VPS using a restricted Mail Send key and a verified from address.

Frequently Asked Questions about integration-sendgrid

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure SendGrid transactional email on a remote VPS using SSH?▼

SendGrid transactional email on a remote VPS is configured over SSH by applying a restricted API key, verifying a from address, reloading gateways, and running smoke tests. The agent wires the connection directly into the environment file.

What SendGrid API key scope do I need to send transactional mail from Hermes?▼

SendGrid transactional mail from Hermes requires a restricted SG.-prefixed API key with Mail Send scope. You must also provide a verified from address to complete the sender identity check during setup.

Can I connect an MCP server for email delivery instead of direct REST API?▼

An MCP server for email delivery is supported as an opt-in community path alongside default direct REST API usage. You can request the community MCP registration when wiring SendGrid to your self-hosted Hermes agent.

Is SendGrid setup idempotent and rollback-safe for repeated Hermes environment updates?▼

SendGrid setup is fully idempotent and rollback-safe for Hermes environment updates. It validates scopes, checks sender verification, and performs safe re-runs so the integration can be repeated without corrupting server config.

What happens if my SendGrid from address is not verified before wiring Hermes?▼

If your SendGrid from address is not verified, the Hermes wiring fails the sender verification check. The smoke test validates this identity first, preventing failed email delivery from your VPS deployment.
